Editor's Synopsis
Researchers from Perplexity and academic collaborators conducted a field study comparing a conversational AI assistant with an autonomous AI agent, finding that AI agents don't merely accelerate knowledge work — they fundamentally change its nature. The study highlights a key distinction: a conversational assistant returns information quickly (summaries, links) that a user must then act on manually, while an autonomous agent delivers completed work products such as built spreadsheets, drawn charts, and draft memos, albeit with a longer processing time.
The research, published in Harvard Business Review, suggests that AI agents broaden the scope of knowledge work by shifting what counts as a task boundary. Rather than simply helping workers find information faster, agents take on multi-step workflows end to end. This has significant implications for competitive strategy, change management, and how organizations think about productivity and the evolving role of human judgment in an AI-augmented workplace.
